commit 5df867145f8adad9e5cdf9d67db1fbc0f71351e9 upstream.

Depending on include order:

    include/linux/of_clk.h:11:45: warning: ‘struct device_node’ declared inside parameter list will not be visible outside of this definition or declaration
     unsigned int of_clk_get_parent_count(struct device_node *np);
						 ^~~~~~~~~~~
    include/linux/of_clk.h:12:43: warning: ‘struct device_node’ declared inside parameter list will not be visible outside of this definition or declaration
     const char *of_clk_get_parent_name(struct device_node *np, int index);
					       ^~~~~~~~~~~
    include/linux/of_clk.h:13:31: warning: ‘struct of_device_id’ declared inside parameter list will not be visible outside of this definition or declaration
     void of_clk_init(const struct of_device_id *matches);
				   ^~~~~~~~~~~~

Fix this by adding forward declarations for struct device_node and
struct of_device_id.

clk: Extract OF clock helpers in

2018-05-02T15:31:07+00:00

The use of of_clk_get_parent_{count,name}() and of_clk_init() is not
limited to clock providers.

Hence move these helpers into their own header file, so callers that are
not clock providers no longer have to include .
